As you can see, in the initialization of the grid the canSort is disabled and the sorting is disabled in the grid:

I re-enable the sorting again and notice (in the screenshot of the previous blogpost that the sorting is done by clicking the column headers. We can sort Ascending and Descending. But wouldn’t it be nice if we had some ascending and descending arrows next to the column headers? Look at the sample below where I introduce the small arrows. (thanks to Alexander Prokofyev)
